Description

La présente invention concerne un dispositif de découpe automatisée de pains en tranches.The present invention relates to a cutting device automated sliced breads.

Des dispositifs de découpe automatisée de pains en tranches sont bien connus. On les rencontre dans la plupart des boulangeries artisanales et également en grandes surfaces. Ces dispositifs, ou trancheuses automatiques de pains, fonctionnent selon le principe suivant : L'utilisateur du dispositif y introduit le pain qu'il désire couper en tranches en le plaçant dans un compartiment disposé entre un élément d'entraínement du pain et un ensemble de lames parallèles destinées à trancher ledit pain. L'utilisateur met ensuite le dispositif en marche en enclenchant l'interrupteur prévu à cet effet, ce qui entraíne la mise en mouvement alternatif des lames et en mouvement de translation transversalement à la direction des lames de l'élément d'entraínement du pain. Le pain est dès lors déplacé par cet élément d'entraínement en direction des lames et la découpe commence lorsqu'il entre en contact avec ces dernières. L'utilisateur récupère son pain découpé en tranches dans un compartiment disposé du côté des lames opposé à celui où est disposé le compartiment de chargement du pain dans le dispositif. Il ne reste plus alors à cet utilisateur qu'à emballer le pain découpé.Automated cutting devices for breads Slices are well known. We meet them in most craft bakeries and also in supermarkets. These devices, or automatic bread slicers, operate according to the following principle: The user of the device introduces the bread he wants cut into slices by placing it in a compartment arranged between a drive element of the bread and a set of parallel blades slicing said bread. The user then puts the device into by switching on the switch provided for this purpose, which leads to alternating movement of the blades and in translation movement transversely to the direction of the blades of the drive element of the bread. The bread is therefore displaced by this training element in direction of the blades and cutting begins when it comes in contact with these. The user recovers his sliced bread in a compartment arranged on the side of the blades opposite to that where is arranged the bread loading compartment in the device. He ... not this user is left more than to pack the cut bread.

Dans les dispositifs traditionnels de tranchage automatique de pains, la puissance du moteur animant l'élément d'entraínement du pain est constante et par conséquent ne peut être adaptée au type de pain dont le tranchage est souhaité, en fonction de la vitesse de déplacement de l'élément d'entraínement du pain pendant l'opération de découpe. Ceci pose un problème quant à la qualité de la découpe du pain. En effet, dans le cas d'un pain à croûte souple et mie molle, une puissance trop élevée fournie par le moteur et donc une vitesse trop importante de l'élément d'entraínement du pain engendreront une pression trop forte sur le pain lors du début de sa découpe et dès lors un écrasement de ce dernier sur les lames ainsi qu'un déchirement de la mie en cours de découpe. La qualité de la découpe du pain sera dès lors pauvre puisque les tranches présenteront un aspect écrasé du côté de leur bord d'attaque par les lames ainsi que des déchirures de leur mie. II en va de même avec un pain présentant une croûte dure et une mie molle car dans ce cas, une puissance trop élevée du moteur et donc une vitesse trop importante de l'élément d'entraínement du pain lors du début de la découpe entraíneront également un excès de pression sur la croûte lors de son attaque par les lames et par conséquent une brisure de la croûte contre les lames et un émiettement consécutif de cette dernière, suivi d'un déchirement de la mie comme exposé ci-dessus en cours de découpe. A l'opposé, dans le cas d'un pain à croûte et mie fermes, une puissance trop faible de moteur et donc une vitesse trop lente du dispositif de pousse du pain pourra avoir pour conséquence un défaut de pression sur le pain en cours de découpe et dès lors un frottement des lames de la machine trop prolongé sur la mie du pain qui entraínera un émiettement et un boulochage de cette dernière par les lames. Ceci sera également le cas lorsqu'un pain à croûte dure et mie ferme est découpé puisque la découpe de la croûte en début de découpe sera elle correcte mais celle de la mie par la suite sera également trop lente et pourra donc entraíner l'apparition des émiettement et boulochage susmentionnées.In traditional devices automatic slicing bread, the power of the motor animating the drive element of the bread is constant and therefore can not be adapted to the type of bread slicing is desired, depending on the speed of movement of the element driving the bread during the operation of cutting. This poses a problem as to the quality of the cutting of the bread. Indeed, in the case of soft and soft crust bread, a too high power supplied by the motor and therefore a speed too important element of the training element of the bread will engender a too strong a pressure on the bread at the beginning of its cutting and therefore a crushing of the latter on the blades and a tearing of the mie being cut. The quality of the bread cut will be poor because the slices will have a crushed appearance on the side of their leading edge by the blades as well as rips of their crumb. II the same with a bread with a hard crust and a crumb soft because in this case, too high engine power and therefore a excessive speed of the element of training bread at the beginning cutting will also cause excessive pressure on the crust during his attack by the blades and therefore a breaking of the crust against the blades and a subsequent crumbling of the latter, followed by a tearing of the crumb as explained above during cutting. In contrast, in the case of firm crust bread, a motor power too low and therefore a speed too slow breadmaking device may result in a defect of pressure on the bread being cut and therefore a friction of blades of the machine too long on the bread crumbs that will cause a crumbling and pilling of the latter by the blades. This will be also the case when a stiff and hard crust bread is cut since cutting the crust at the beginning of cutting will be correct but that of the crumb later will also be too slow and can therefore lead to the appearance of the abovementioned crumbling and pilling.

On a tenté de résoudre ce problème d'inadaptation de la puissance du moteur animant l'élément d'entraínement du pain à la nature de celui-ci en munissant l'élément d'entraínement d'un système de contrôle de la puissance de son moteur et donc de la vitesse de l'élément d'entraínement du pain et consécutivement de la pression qu'il exerce sur le pain en cours de découpe. Un tel système peut consister en un levier permettant à l'utilisateur du dispositif de commander manuellement l'élément d'entraínement du pain dans la machine ou en une commande électrique permettent d'augmenter ou de réduire la puissance du moteur animant l'élément d'entraínement durant la découpe dudit pain.An attempt has been made to solve this problem of maladjustment motor power animating the drive element of the bread to the nature of it by providing the training element with a system of control of the power of its engine and therefore the speed of the element training of bread and consecutively the pressure it exerts on the bread being cut. Such a system can consist of a lever allowing the user of the device to manually control the element of training bread in the machine or in a command can increase or decrease the power of the motor animating the training element during the cutting of said bread.

Néanmoins, ces systèmes posent un autre problème puisqu'ils demandent toujours une intervention de l'utilisateur pour les commander et par conséquent d'une part une certaine expérience de celui-ci en matière de types de pains et de conditions de découpe optimales associées à chacun de ces types et d'autre part une mobilisation de l'utilisateur pendant tout le temps de découpe du pain pour commander le système de contrôle de l'élément d'entraínement de ce pain dans le dispositif.Nevertheless, these systems pose another problem since they always require user intervention for order and therefore on the one hand some experience of the latter in terms of bread types and cutting conditions optimal for each of these types and on the other hand a mobilization of the user during the whole time of bread cutting to control the control system of the drive element of this bread in the device.

La présente invention résout les problème susmentionnés et pallie les inconvénients qui y sont associés en proposant un dispositif de découpe automatisée de pains en tranches dans lequel la vitesse de l'élément d'entraínement du pain est adaptée de manière automatique au type de pain à découper et en particulier à la dureté de sa croûte et la fermeté de sa mie, et ce tout au long de l'opération de découpe.The present invention solves the aforementioned problems and overcomes the disadvantages associated with it by proposing a device automated cutting of sliced breads in which the speed of the training element of the bread is automatically adapted to type of bread to cut and especially to the hardness of its crust and the firmness of its crumb, and this throughout the cutting operation.

Dès lors, l'invention consiste en un dispositif de découpe automatisée d'un pain en tranches comprenant un élément d'entraínement du pain agencé pour être déplacé au moyen d'un moyen de déplacement couplé audit élément entre une première position de recul dans laquelle le pain à découper peut être chargé dans le dispositif et une seconde position d'avancement dans laquelle le pain découpé peut être retiré du dispositif, celui-ci comprenant en outre un ensemble de lames de découpe du pain disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient, l'élément d'entraínement du pain étant agencé pour, lorsque le dispositif est en fonctionnement, entraíner le pain dans un mouvement de translation vers et au travers de l'ensemble de lames entre la première et la seconde position dudit élément, le dispositif comprenant encore un moyen agencé pour réguler automatiquement la puissance fournie par le moteur en fonction de la vitesse et/ou de l'accélération du mouvement de translation de l'élément d'entraínement du pain pendant l'opération de découpe de celui-ci.Therefore, the invention consists of a cutting device automated slice of bread with an element training bread arranged to be moved by means of a means displacement coupled to said element between a first position of recess in which the carving bread can be loaded into the device and a second advancement position in which the cut bread can be removed from the device, the device further comprising a set bread cutting blades arranged substantially parallel to the to each other and arranged to be animated by a movement alternating back and forth, the training element of the bread being arranged for, when the device is in operation, drive the bread into a translation movement to and through the blade assembly between the first and the second position of said element, the device further comprising means arranged to automatically regulate the power supplied by the engine according to the speed and / or the acceleration of the translational movement of the drive element bread during the cutting operation thereof.

Grâce au moyen de régulation automatique de puissance du moteur en fonction de la vitesse et/ou de l'accélération de l'élément d'entraínement du pain du dispositif selon l'invention, la découpe d'un pain est toujours optimisée selon le type de pain en question. En effet, lorsque le pain oppose une résistance importante aux lames en début de découpe, c'est à dire lorsque la croûte du pain est dure, la vitesse de déplacement de l'élément d'entraínement sera rapidement et fortement réduite et cette décélération forte et rapide sera repérée par le moyen de régulation qui diminuera la puissance fournie par le moyen de déplacement de l'élément d'entraínement et la croûte sera dès lors découpée sans qu'elle ne soit brisée par écrasement du pain sur les lames en raison d'une trop grande vitesse et/ou accélération de déplacement de l'élément d'entraínement du pain. Une fois l'épaisseur de la croûte franchie par les lames et la découpe de la mie entamée, la résistance du pain aux lames diminue et la vitesse de déplacement de l'élément d'entraínement du pain augmente. Si cette vitesse ne dépasse pas une valeur seuil prédéterminée, la puissance fournie par le moyen de déplacement de l'élément d'entraínement est augmentée par paliers jusqu'à ce que ladite valeur seuil soit atteinte. Ainsi, quelle que soit la consistance molle ou ferme du pain, la vitesse et/ou l'accélération de déplacement de l'élément d'entraínement dudit pain sont contrôlées pour éviter un déchirement de la mie en raison d'une vitesse ou une accélération excessive ou au contraire l'apparition d'un boulochage de cette mie de par un déplacement trop lent de l'élément d'entraínement du pain et au frottement consécutif excessif des lames sur la mie. Dès lors, plus aucun phénomène d'écrasement de croûte ni de déchirure de mie n'est observé grâce au dispositif selon l'invention.Thanks to the automatic power control the engine according to the speed and / or acceleration of the element of driving the bread of the device according to the invention, the cutting of a bread is always optimized according to the type of bread in question. Indeed, when the bread opposes an important resistance to the blades at the beginning of cutting, ie when the crust of the bread is hard, the speed of displacement of the training element will be quickly and strongly reduced and this strong and fast deceleration will be spotted by means of regulation that will decrease the power provided by the means of movement of the training element and the crust will be cut without breaking it by crushing the bread on the blades due to excessive speed and / or acceleration of moving the drive element of the bread. Once the thickness of the crust crossed by the blades and the cutting of the cut corn, the resistance of the bread to the blades decreases and the speed of movement of the element of training bread increases. If this speed does not exceed not a predetermined threshold value, the power supplied by the means of movement of the drive element is increased in steps until said threshold value is reached. So, whatever the soft or firm consistency of bread, speed and / or acceleration of movement of the drive element of said bread are controlled for avoid cracks in the crumb due to speed or excessive acceleration or on the contrary the appearance of a pilling of this grit by a slow movement of the drive element of the bread and the consequent friction excessive blades on the crumb. Since then, no crust crushing or creasing cracks is observed thanks to the device according to the invention.

L'invention va à présent être décrite plus en détails au moyen d'un exemple illustrant un mode de réalisation non limitatif de sa portée et en référence à la figure 1 jointe représentant une vue schématique en coupe transversale d'un dispositif selon l'invention.The invention will now be described in more detail in by way of an example illustrating a non-limiting embodiment of its scope and with reference to Figure 1 attached showing a view schematic in cross section of a device according to the invention.

Le dispositif 1 selon l'invention comporte un châssis 2 comprenant une table de découpe 3 d'un pain 4 que l'on dispose dans un compartiment de chargement 5 du dispositif. Celui-ci comprend encore un élément d'entraínement 7 du pain 4 et un ensemble de lames 8 disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient pour découper le pain 4 en tranches. Un presse pain 6 est également prévu, constitué d'une lame exerçant une pression sur le dessus du pain pour éviter son tressaillement pendant l'opération de découpe Du côté de l'ensemble de lames 8 opposé au compartiment de chargement 5 du pain 4 est prévu un compartiment 9 de déchargement du pain 4 coupé en tranches. L'élément d'entraínement 7 du pain 4 est agencé pour être déplacé selon un mouvement de translation parallèlement à la table de découpe 3 et transversalement à l'ensemble de lames 8 entre une première position de recul dans laquelle un pain 4 peut être introduit dans le compartiment de chargement 5 et une seconde position d'avancement dans laquelle l'élément d'entraínement 7 du pain est adjacent à l'ensemble de lames 8 et le pain 4 coupé en tranches et disposé dans le compartiment 9 de déchargement peut être retiré du dispositif 1. Le déplacement de l'élément d'entraínement 7 est effectué au moyen d'un moteur électrique 10 comprenant un rotor et un stator, couplé audit élément d'entraínement 7 par un vérin 11 actionnant un bras articulé 12 comprenant un premier élément 12a articulé par une charnière ou une rotule à un second élément 12b, une première extrémité du bras 12 pouvant pivoter autour d'un pivot 13 et une seconde extrémité dudit bras 12 étant connectée à l'élément d'entraínement 7. Alternativement au moteur électrique 10, un autre moyen de déplacement de l'élément d'entraínement 7 peut être prévu, par exemple une source ou un réservoir d'air comprimé actionnant par exemple un vérin pneumatique.The device 1 according to the invention comprises a chassis 2 comprising a cutting table 3 of a bread 4 that is available in a loading compartment 5 of the device. This one still includes a drive element 7 of the bread 4 and a set of blades 8 disposed substantially parallel to each other and arranged to be animated by an alternating back and forth movement for cut the bread 4 into slices. A bread press 6 is also provided, consisting of a blade exerting a pressure on the top of the bread for avoid his thrill during the cutting operation the blade assembly 8 opposite the load compartment 5 of the bread 4 is provided a compartment 9 for unloading bread 4 cut into slices. The training element 7 of the bread 4 is arranged to be moved in a translational motion parallel to the table of cut 3 and transversely to the set of blades 8 between a first recoil position in which a bread 4 can be introduced into the loading compartment 5 and a second advancement position wherein the training element 7 of the bread is adjacent to the set of blades 8 and the bread 4 cut into slices and disposed in the unloading compartment 9 can be removed from device 1. The movement of the training element 7 is effected by means of a electric motor 10 comprising a rotor and a stator, coupled to said driving element 7 by a jack 11 actuating an articulated arm 12 comprising a first element 12a articulated by a hinge or a ball joint to a second element 12b, a first end of the arm 12 pivotable about a pivot 13 and a second end of said arm 12 being connected to the training element 7. Alternatively to the electric motor 10, another means of moving the element 7 can be provided, for example a source or a compressed air tank actuating for example a pneumatic cylinder.

La puissance fournie par le moteur 10 couplé à l'élément d'entraínement 7 du pain 4 pendant le fonctionnement du dispositif 1 est régulée automatiquement par un moyen de régulation 14 en fonction de la vitesse dudit élément d'entraínement 7, laquelle est conditionnée par la résistance que le pain 4 et le presse pain 6 opposent à l'ensemble de lames 8 pendant l'opération de découpe dudit pain. En effet, le presse pain 6 en exerçant une pression sur ledit pain 4 augmente la résistance que celui-ci oppose par lui-même à l'ensemble de lames 8. Le moyen de régulation 14 est agencé pour mesurer la vitesse de rotation du rotor dans le stator du moteur 10 pour déterminer la vitesse du mouvement de translation de l'élément d'entraínement 7 du pain 4 et est également agencé pour comparer la vitesse mesurée à une vitesse prédéterminée et pour augmenter ou diminuer la puissance du moteur 10 lorsque cette vitesse mesurée est respectivement inférieure ou supérieure à la vitesse prédéterminée.The power provided by the motor 10 coupled to the element 7 of the bread 4 during the operation of the device 1 is automatically regulated by a regulating means 14 as a function of the speed of said driving element 7, which is conditioned by the resistance that the bread 4 and the bread press 6 oppose to the whole blades 8 during the cutting operation of said bread. Indeed, the press bread 6 by exerting pressure on said bread 4 increases the resistance that it opposes by itself to the set of blades 8. The means of regulator 14 is arranged to measure the rotational speed of the rotor in the stator of the motor 10 to determine the speed of the movement of translation of the training element 7 of the bread 4 and is also arranged to compare the measured speed to a predetermined speed and to increase or decrease the power of the motor 10 when this measured speed is respectively lower or higher than the speed predetermined.

Si un autre moyen de déplacement de l'élément d'entraínement 7 est utilisé, tel qu'une source ou un réservoir d'air comprimé, c'est la vitesse de déplacement de l'élément d'entraínement 7 elle-même qui pourra être directement mesurée par le moyen de régulation 14, par exemple grâce à des capteurs de position tels que des cellules photoélectriques disposées sur le parcours de l'élément d'entraínement 7. If another way of moving the element 7 is used, such as a source or an air tank compressed is the speed of movement of the training element 7 itself which can be directly measured by means of regulation 14, for example by means of position sensors such as photocells arranged on the path of the element Training 7.

Ainsi, quelle que soit le type de pain découpé, la vitesse de cette découpe est en permanence optimisée par le dispositif selon l'invention. Lorsqu'un pain à croûte dure ou au contraire très souple est mis à découper dans le dispositif selon l'invention et que la croûte atteint l'ensemble de lames 8, une résistance très importante au mouvement de translation de l'élément d'entraínement 7 du pain est opposée par la croûte à la découpe par l'ensemble de lames 8, soit en raison de la dureté de ladite croûte ou de la compression du pain à croûte souple. Même dans le cas d'un pain d'un autre type, une telle résistance peut être provoquée, principalement alors par la pression exercée par le presse pain sur ledit pain. Cette résistance entraíne un pic d'intensité du courant consommé par le moteur 10 qui indique que la puissance de ce moteur et donc le courant consommé doivent être réduits pour éviter que la croûte du pain ne soit écrasée contre les lames en raison d'une pression trop forte exercée par l'élément d'entraínement 7 sur le pain. Ce pic d'intensité correspond à une valeur prédéterminée et peut être mesuré et le courant ainsi donc que la puissance du moteur 10 peuvent en réaction être fortement réduits jusqu'à une autre valeur prédéterminée pour que la découpe de la croûte du pain soit effectuée de manière optimale sans écrasement. C'est pourquoi, le moyen de régulation 14 du dispositif 1 selon l'invention est également agencé pour diminuer l'intensité du courant consommé par le moteur 10 jusqu'à une première valeur prédéterminée lorsque cette intensité dépasse une seconde valeur prédéterminée.Thus, whatever the type of bread cut, the speed of this cutting is permanently optimized by the device according to the invention. When a bread with hard crust or on the contrary very flexible cut into the device according to the invention and that the crust reaches the blade assembly 8, a very important resistance to the movement of translation of the drive element 7 of the bread is opposed by the crust cut by the blade assembly 8, either because of the hardness of said crust or compression of soft crust bread. Even in the case of bread of another type, such resistance may to be provoked, mainly then by the pressure exerted by the press bread on said bread. This resistance causes a peak of intensity of the current consumed by the motor 10 which indicates that the power of this motor and therefore the current consumed must be reduced to prevent the crust of the bread is crushed against the blades because of excessive pressure exerted by the training element 7 on the bread. This Peak intensity corresponds to a predetermined value and can be measured and the current well so that the power of the motor 10 can in response to be strongly reduced to another predetermined value so that the crust of the bread is cut so optimal without crushing. That is why the means of regulation of the device 1 according to the invention is also arranged to reduce the intensity of the current consumed by the engine 10 to a first predetermined value when this intensity exceeds a second value predetermined.

Dans le cas où un autre moyen de déplacement que le moteur 10 est utilisé, tel qu'une source ou un réservoir d'air comprimé, le pic d'intensité susmentionné est remplacé par un pic de pression de l'air utilisé pour déplacer l'élément d'entraínement 7. La puissance régulée est également dans ce cas la pression de l'air en question.In the case where another means of movement than the motor 10 is used, such as a source or a reservoir of compressed air, the aforementioned peak of intensity is replaced by a peak of air pressure used to move the drive element 7. The regulated power is also in this case the air pressure in question.

Une fois la découpe de la croûte du pain effectuée, l'ensemble de lames 8 attaque la découpe de la mie du pain 4. Si la vitesse de déplacement de l'élément d'entraínement 7 et donc de découpe du pain 4 est alors inférieure à une valeur prédéterminée, le moyen de régulation 14 augmentera la puissance du moteur 10 jusqu'à ce que cette valeur soit atteinte, de sorte à éviter qu'une vitesse trop lente ne conduise à un frottement excessif de l'ensemble de lames 8 sur la mie du pain 4 et à l'apparition consécutive d'un boulochage de cette mie. Si d'aventure, dans le cas par exemple d'un pain à mie très légère, la valeur prédéterminée de la vitesse de découpe du pain était dépassée, le moyen de régulation 14 commanderait une diminution de la puissance du moteur 10 pour éviter tout déchirement de la mie dû à une vitesse ou à une accélération de déplacement de l'élément d'entraínement 7 excessive. Le moyen de régulation 14 est de plus agencé pour provoquer une inversion du sens de déplacement de l'élément d'entraínement 7 du pain 4 lorsqu'il atteint sa première ou sa seconde position. Cette inversion peut être provoquée de plusieurs manières Elle peut être commandée par au moins une cellule photoélectrique (non illustrée) agencée pour repérer l'arrivée de l'élément d'entraínement 7 dans sa première ou sa seconde position ou alternativement en prévoyant que le moyen de régulation 14 soit agencé pour mesurer le nombre de tours effectués par le rotor du moteur 10 dans son stator et pour provoquer ladite inversion depuis l'une des première ou seconde positions de l'élément d'entraínement 7 lorsque ledit nombre de tours atteint une valeur prédéterminée depuis l'autre des première ou seconde positions de l'élément d'entraínement 7. Alternativement encore, ou concomitamment, l'inversion en question peut être provoquée depuis l'une des première ou seconde positions de l'élément d'entraínement 7 lorsque l'intensité du courant consommé par le moteur 10 dépasse une valeur seuil prédéterminée apparaissant lors de la butée de l'élément d'entraínement 7 contre un arrêt disposé au niveau de sa première et/ou seconde positions. Once the crust of the bread has been cut, the set of blades 8 attacks the cutting of the crumb of bread 4. If the speed of movement of the training element 7 and therefore of cutting of the bread 4 is then less than a predetermined value, the regulating means 14 will increase the power of the motor 10 to this value is reached, so as to prevent a speed too much slow operation will lead to excessive friction of the blade assembly 8 breadcrumb 4 and the subsequent appearance of a pilling of this mie. If, for example, in the case of a very light bread, the predetermined value of the cutting speed of the bread was exceeded, the regulating means 14 would control a decrease in power motor 10 to prevent cracks in the crumb due to speed or at an acceleration of displacement of the training element 7 excessive. The regulating means 14 is furthermore arranged to provoke a reversal of the direction of movement of the driving element 7 of the bread 4 when it reaches its first or second position. This inversion can be provoked in many ways It can be controlled by at least one photocell (not shown) arranged to locate the arrival of the training element 7 in its first or second position or alternatively by providing that the control means 14 is arranged to measure the number of turns performed by the rotor of the motor 10 in its stator and to provoke said inversion from one of the first or second positions of the driving element 7 when said number of turns reaches a predetermined value from the other of the first or second positions of the training element 7. Alternatively again, or concomitantly, the inversion in question may be provoked one of the first or second positions of the training element 7 when the intensity of the current consumed by the motor 10 exceeds a predetermined threshold value occurring during the abutment of the element 7 against a stop at the level of its first and / or second positions.

En pratique, le moyen de régulation 14 pourra comprendre un circuit de contrôle de la puissance fournie par le moteur 10 commandé par une puce électronique programmée pour, à partir d'une mesure par un ampèremètre de l'intensité du courant consommé par le moteur 10 et du nombre de tours par unité de temps du rotor dudit moteur 10 dans son stator, indiqué par exemple au moyen d'un disque de comptage couplé audit rotor, calculer la vitesse et/ou l'accélération de l'élément d'entraínement 7 et commander le circuit de contrôle de puissance susmentionné. Le moyen de régulation 14 est relié au moteur 10 par un premier câble électrique 15 transmettant les informations d'intensité de courant et de vitesse de moteur mentionnées ci-dessus et un second câble électrique 16 alimentant le moteur 10 en électricité.In practice, the regulating means 14 may comprise a control circuit of the power supplied by the controlled motor 10 by an electronic chip programmed for, from a measurement by an ammeter of the intensity of the current consumed by the motor 10 and the number of revolutions per unit time of the rotor of said motor 10 in its stator, indicated for example by means of a coupled counting disc rotor audit, calculate the speed and / or acceleration of the element 7 and control the power control circuit above. The regulating means 14 is connected to the motor 10 by a first electrical cable 15 transmitting the intensity information of current and motor speed mentioned above and a second electric cable 16 supplying the motor 10 with electricity.
